Method Detail

getDesiredState

S getDesiredState(S state,
                  ExecutionContext context)

Determines the desired state of the FiniteStateMachine for the Event given the current state of the FiniteStateMachine.

Parameters:

state - the current state of the FiniteStateMachine

context - the ExecutionContext for the Event

Returns:

the desired state of the FiniteStateMachine or null if no transition is required
